An Active Optical Cable (AOC) is a factory-integrated cable assembly that combines optical transceivers and fiber into a single cable, enabling high-speed optical connectivity between network devices.

DAC cables use copper conductors and are typically limited to shorter distances. Active optical cable AOC solutions use optical fiber and support longer distances with lighter weight and improved signal integrity.

The 100G QSFP to 4×25G SFP28 Active Optical Cable supports:

- Up to 70 meters on OM3 multimode fiber - Up to 100 meters on OM4 multimode fiber
